The references to the painting are very important and students will definitely find them interesting. However, our topic is, always, the lesson. So, by our method and the specific steps we propose, we should approach the lesson.
We chose a work of art to reach the conclusions we want, because a work of art both explicitly states some facts, but also implies others leaving the viewer’s imagination free to reach conclusions. In our lesson, we should reach and concentrate on these conclusions concerning our scientific topic. We should, for example, talk about their characteristics, their nature, their composition, and behavior (eg concerning electrons, what is their motion when voltage is applied to them, what is the behavior of one chemical element if it is mixed with another, what is water’s behavior when its temperature changes and falls below 0, or if it rises above 100 ° C, etc)
